Manuaalkäigukast, often referred to as a manual transmission or stick shift, is a type of automotive gearbox that requires the driver to manually select each gear. Unlike an automatic transmission, which changes gears independently, a manual transmission relies on the driver operating a clutch pedal and a gear shifter. The clutch pedal disengages the engine from the transmission, allowing the driver to smoothly transition between gears by moving the shifter.

The primary components of a manual transmission include a clutch, input shaft, output shaft, gears, and synchronizers. The gears are arranged in specific ratios to provide different levels of torque and speed. Synchronizers, or synchros, are crucial for ensuring smooth gear changes by matching the rotational speed of the gears before they engage.

Driving a vehicle with a manual transmission offers several advantages, including greater control over the vehicle's performance, potentially better fuel efficiency, and a more engaging driving experience for some enthusiasts. However, it also requires more driver input and practice to master, especially in stop-and-go traffic.

The operation of a manual transmission involves a sequence of actions: pressing the clutch pedal, moving the gear shifter to the desired gear, and then releasing the clutch pedal while coordinating with throttle input. This process is repeated as the vehicle accelerates or decelerates. While less common in modern passenger cars in some regions due to the prevalence of automatics, manual transmissions are still popular in performance vehicles, trucks, and in many markets worldwide.
